G'day all
Somewhat relevant... Part of my benchtesting exersize on my DIY beowulf was a comparison between running the onboard FastEthernet v's adding an Intel 1000MT GigaE adapter.
I changed the MPI config to ensure the MPI traffic had the GigaE to itself and "other" traffic went via the FastE.
I ran the full MPI perftest suite. Sample graphs on this web page:

-> Computing
It was indeed "a bit" faster.
There's some NetPipe results in there too. I can provide more details if any one is interested.
Note: I know magic can be worked with the Intel driver but this is "vanilla" ATM.
Cheers
Steve
